How are migraine and vertigo defined?

Answer

Migraine headaches are recurrent headaches that are often accompanied by nausea and light sensitivity and that are separated by symptom-free intervals. The headaches typically have a throbbing quality, are relieved after sleep, and may be accompanied by visual symptoms, dizziness, or vertigo. Patients often have a family history of migraine.

Migraine can be divided into 2 categories: migraine without aura (common migraine, 90% of migraine headache cases) and migraine with aura (classic migraine, 10% of cases).

Vertigo is an illusion of movement of the environment or of the patient in relation to the environment.
